Present disclosure relates to an E-liquid supply mechanism and an electronic cigarette having the same. The E-liquid supply mechanism includes a stationary portion, a movable portion, and an E-liquid bottle. Stationary portion includes an E-liquid bottle lid, an E-liquid supply mechanism body, and an E-liquid supply intake tube. E-liquid supply mechanism body is attached to E-liquid bottle lid. E-liquid supply intake tube is attached to a low end of E-liquid supply mechanism body. Movable portion is positioned inside of E-liquid supply mechanism body and includes a press button, a first E-liquid tube, a supply piston, a second E-liquid tube, a spring, and a steel ball. First E-liquid tube is attached to the press button. The supply piston is attached to the first E-liquid tube. The second E-liquid tube is attached to the supply piston. The spring positioned under the second E-liquid tube, and the steel ball positioned under the spring.

A product includes a container, and an indicator carried inside the container, and including an air-reactive material and a protective material on the air-reactive material, and having a first visible characteristic with the protective material, and a second visible characteristic when exposed to air without the protective material. A package including the product, and a method for making the package are also disclosed.

A product includes a bottle, and an indicator that is carried in a relief in an interior surface of at least one of a shoulder of the bottle or a neck of the bottle, and that is adapted, upon contact with air, irreversibly to change a characteristic of the indicator that is visible from outside of the bottle to indicate to a user that the product has been used. A package including the product, and a method for making the package are also disclosed.

A method of tracking liquid consumption for a bottle assembly may include sensing a dispensing operation of an external liquid dispenser. The method may further include determining an identity of the external liquid dispenser based on sensing the dispensing operation of the external liquid dispenser. The method may also include adjusting the flow assembly in response to determining the identity of the external liquid dispenser. The flow assembly may define a filter position and a bypass position. The method may also include measuring liquid data of the liquid reservoir following adjusting the flow assembly.

A thermoplastic bottle is provided that has a sidewall having an exterior surface that defines a plane curve. The sidewall is joined with a base and an upper portion with a mouth to define an interior volume. The mouth has a set of threads to engage a cap for selectable closure. A handle is integrally formed in the sidewall that defines an aperture in the bottle. A set of lateral ribs on the handle enhance gripping. The bottle includes a set of identifying design elements that include at least one of one or more waves, delineating lines, and a shape of the bottle. One or more indicia in the form of decals may be applied to identify the product in the bottle by name, and to provide usage and safety information.

A modular utility container 112 comprises a hollow body 112 for storing a liquid through an opening 116 formed at a top end of the hollow body 114. A neck 118 extends from the opening 116 and has a narrower cross-section than hollow body 114 and a tapered-shaped structure. Container 112 further comprises a base 122 supporting the hollow body 112. Base 122 is made substantially curved in an inward dome-shaped structure, configured to engage with a sensor 206 to determine the level of liquid present within utility container 112. Container 112 is configured for use with a real-time liquid-level detection system 300 to eliminate manual monitoring of utility container 112 for determining the liquid level, and details regarding the liquid level of fluid stored in utility container 112 are assessed via a remote means and an inbuilt mobile application. Base 122 has a concave punt with a central flat indentation that enhances the usability and accuracy of ultrasonic liquid level measurement in aluminum bottles. Sensor 206 is, optionally, convex and deforms in response to downward pressure from base 206 to establish contact with substantially all points of engagement. The system ensures stable and repeatable sensor positioning, eliminates air gaps and wave distortions, improves operational efficiency in hotel housekeeping, and maintains bottle strength and manufacturing feasibility.
